- To all 1 071,077?! it may concern:

Be it known that I, TANDY W. ToNEY, a

citizen of the United States, residing at Eu faula, in the county of Barbour and State of Alabama, have invented new and useful Improvements in Condensers, of which the folthe present case the liquidization of the ex-' l1aust-steam is secured by water, the water being heated by the exhaust-steam, by reason of which there is an equalization of temperature of the two constituents. The resultant mixture, composed of liquidized steam and water heated by the steam, is supplied to the boiler of the engine, whereby economy is assured, for, as will be apparent, I liquidize the exhaust-steam and return it after liquidization to the boiler.

By the invention I can save large quantities of fuel and water.

From what has been stated it will be evil dent that the device is for the liq'uidizing of exhaust-steam and returning it to a boiler,

as hereinafter explained.

In the drawings forming a part of this specification I illustrate a simple form of em bodiment of my invention, which to enable those skilled in the art to practice said inven tion I will describe in detail in the following description, while the novelty of the invention will be included in the claims succeeding said description.

In the said drawings, Figure 1 is a perspective view of the apparatus. Fig. 2 is a longitudinal sectional elevation of the same.

Like characters refer to like parts throughout the different views.

In the embodiment of the apparatus illus trated the same includes a tank, as 2, of any suitable size and material and which is adapted to contain water to, say, in the neighborhood of about threefourths of its height. Associated with the tank 2 is what may conveniently be considered an exhaust-steam pipe 3, adapted in practice to-be connected with the exhaust of a steam-engine. (Not shown.) For this purpose the exhauststeam pipe may have at one end a union or coupling, as 4, of some suitable kind. The apparatus has a number of pipes or conduits and their equivalents, and these for convenience are made of separable sections, such as nipples, Ts, elbows, and the like. I do not deem it necessary, however, to go into a detailed description of these points, although by making the conduits or pipes and cooperating parts in sections they may be more readily separated when necessary to take down the apparatus or set it up.

From the exhaust-steam pipe 3 at least one branch pipe extends. have shown three of these branch pipes, and as they are the same in construction each will be denoted by the character 5. The branch pipe 5 are substantially of inverted-U form, the outer legs thereof being connected at their lower ends with the steam-exhaust pipe 3, while the inner legs thereof are extended downwardly through the top of the tank and are connected at their lower ends with the pipe system 6. The pipe system 6 includes a circuit-like frame part and a cross-piece uniting the side bars of said frame part. To the end members of the pipe system 6 the terminal branch pipes 5 are connected, while the intermediate branch pipe is connected with the cross-piece. The pipe system, made up of the circuit or continuous-like part and the cross-bar uniting the side bars thereof, is perforated for the emission of steam, which traverses the same, while the inner legs of the inverted-U-shaped branch pipes 5 are perforated for a like purpose. The perforations in the branch pipes extend. from the bottom for about in the neighborhood of two-thirds of the height of said branch pipes. The pipe system 6 is contiguous to the bottom of the tank 2 and is located within the same, the steam-exhaust pipe 3 being located outside the tank. Exhaust-steam from the engine, therefore, is conducted by the pipe 3 into the branch pipes 5, which in turn convey the exhaust-steam into the tank, where such steam can flow through the perforations in the inner legs of the branch pipes and also through the perforations in the pipe system 6 and in intimate association with the water in the tank, so that such water will liquidize the steam, and the'latter in turn will heat the water, so that there will be an equalization of temperature of the two constituents, the latter being subsequently supplied to the boiler, as will hereinafter appear.

I will now set forth the means illustrated for supplying the steam-liquidizing water to the tank 2. i

A water-supply pipe is shown at As a matter of fact I connection with a main.

7 and as having or terminating in a transverse head 8. From this head 8 the three pipes 9 are shown as extending, one pipe being for each branchpipe 5. The pipes 9 Sup ply water to the pipes 5 above the perforations in the inner legs of the latter, so that I secure initially a liquidization of the steam before the same leaves the branch pipes 5. The

steam and the water, therefore, are brought into intimate mixture before the steam leaves the branch pipes, so that there will be a desirable interchanging of temperature between the two. From the head of the water-supply pipe 7 other pipes, as 10, lead, said pipes 10 being extended through the top of the tank. These pipes 10 are for receiving and conveying any steam that may be in the tank 2 and discharging it into the head 8, where it be comes liquidized, passing from said head into the pipes 9 to be discharged with the water therein into the branch pipes 5, and thence into the tank, where the liquidization of the exhaust-steam is completed. Said pipes 10 are provided with check-valves so arranged that the water from the pipes 9 cannot get into the tank 2; but the steam, if there be any in the tank, can readily flow into the pipes 9 by way of the pipes 10 and head 8.

In the pipes 9 between the head 8 and branch pipes 5 are check-valves of some suitable kind, which prevent exhaust-steam passing to the water-pipe 7, although they freely permit the flow of water to the said branch pipes 5. Any suitable check-valves may be employed for this purpose. Pendent from the exhaust-steam pipe 3 is a draw-ofi cock or valve 11, which may be manipulated to permit the escape of any li uidized steam in said pipe 3. The pipe 7 W1 1 be provided in practice with some suitable means for its For this purpose I have represented a union or coupling 12, and between this coupling or union and the head 8 I interpose a cook or valve located, of course, outside the tank and which may be operated to shut off the supply of water, when occasion requires, to the tank 2 and branch pipes 5.

In adjacence to the main tank 2 is an auxiliary tank 13, from which the water to supply the boiler is directly drawn. At this point I deem it expedient to state that I show neither the boiler nor engine associated therewith, as I consider this to be unnecessary to a full understanding of my invention. Extending from the main tank 2 at verticallyseparated points are pipes 14 and 15. These pipes receive at their entering ends, which are located within the main tank, any steam that might not be liquidized therein and convey such steam into the auxiliary tank, and to insure the liquidization of any such steam the delivery ends of the said pipes 14 and 15 are situated near the bottom of the auxiliary tank. These delivery ends are immersed in the water in the auxiliary tank, the level of such water being at such height to assure this result at all times. r

The pipe 14 discharges water into the tank 13 as well as steam. Its main object, however, is for discharging water into said tank 13, although it will be evident it can also discharge steam into said tank 13 received from the tank 2. I

The feed-water pipe is designated by 16,' and it extends from the tank 13 to conduct the water from such tank to the boiler, and such water, from what has been hereinbefore stated, will be in a hot condition. In some instances it is desirable not to conduct hot water to the boiler primarily, to secure which result I connect a cold-water-feed pipe, as 17, to the feed-water pipe 16 between the boiler and the tank 13. This cold-water supply or feed pipe 17 is provided wit-h a valve, as 18, which is normally closed, but which when occasion requires may be opened to direct cold water into the feed-water pipe 16 and bring about the supply of such cold water to the boiler. The pipe 16 has its entering end below the level of the water in the auxiliary tank. For example, the entering or inlet end of the pipe 16 may be situated in the bottom of said auxiliary tank.

Between the junction of the pipes 16 and 17 and the tank 13 there is a stop-cock 19, which is normally open, but which will be closed when it is desired to supply cold water to'the boiler. I rovide for the supply of cold water to the lEoiler instead of hot water in case the injector or inspirator of the pump should fail to start with the hot water. The cold-water-feed pipe 17 can be supplied from 'a tank (not shown) or in any other desirable way. The exhaust-steam, therefore, from the steam-engine, or a considerable percentage of it, can be employed over and over again, for after it is exhausted it is liquidized, and when liquidized is resupplied to the boiler for further use. I provide means whereby water is utilized to liquidize the exhaust, the steam heating the water, so that the liquid-supply to the boiler will be in a hot or desirable condition. The procedure, as will be understood, is continuous. By the apparatus I effect a great saving of water and fuel.

The system of piping, whichIhave denoted by 6 and which includes in its make-up a circuit'ous body, assures the circuitous flow of steam below the surface of the water in the tank 2, as thereby I secure a desirable effect.

In the drawings I have shown a pipe, as 3*, extending from the exhaust-steam pipe 3. The opposite end of this pipe 3 opens into a jet or injector, as 13 forming a part of the pipe 13". As shown by dotted lines in Fig. 1, this pipe 13 extends downward into the auxiliary tank 13, and it is also connected cock therein. The et or in ector as it .re-

and communicating with said water-pipe.

ceives steam from the pipe 8 from the main pipe 3 serves to force Water from the auxiliary tank 13 into the tank 2, the Water entering the pipe 13 and then the pipe 7, head 8, pipes 9, and finally into pipes 5, from which it flows into the tank 2.

By the arrangement just set forth I secure a continual flow of water into the branch pipes 5 (whenever the engine is operated) for liquidizing the exhaust-steam in said branch pipes and also in the tank 2. The construction described insures an intermixing of the Waters and equalization of the temperature of the same in the two tanks Qand 13 when ever said engine is at work.

Having thus described the invention, what I claim is 1. The combination of a water-tank, an exhaust-steam pipe extended into the tank and perforated in the latter, a water-pipe opening into the non-perforated portion of the exhaust-steam pipe, a second tank in communication with the first tank to receive liquid from the latter, and a feed-pipefor supplying the liquidized steam from the second tank to a boiler.

2. The combination of a watertank, an exhaust-steam pipe extended into said tank and perforated in the latter a Water-pipe opening into the non-perforated portion of the exhaust-steam pipe, a second tank in communication with the first tank to receive liquid from the latter, a feed-pipe for supplying the liquidized steam from the second tank to a boiler, and a water-feed pipe opening into said last-mentioned pipe, each of the two last-mentioned pipes having a handoperable valve.

3. The combination of a water-tank, an exhaust-steam pipe having a branch opening into the tank, that part of the branch within the tank being perforated, a Water-pipe opening into the non-perforated portion of the branch and having a check-valve, and a steam-conveying pipe leading from the tank 4. The combination of a water-tank, an exhaust-steam pipe having a branch leading into the tank, that part of the branch Within the tank being perforated, a perforated system of piping to which the perforated porl tion of the branch is connected andiin said tank, anda water-pipe connected with the non-perforated portion of said branch.

5. The combination of a water-tank, an exhaust-steam pipe having a plurality of substantially inverted-U-shaped branches leading therefrom, the inner legs of the branches extending into the tank and being perforated, a circuit-like system of perforated piping to which the inner of said. branches are connected, and water-pipes opening into the non-perforated portions of said branches.

6. The combination of a water-tank, an exhaust-steam pipe having branches leading into said tank, the portions of the branches within the tank being perforated, a waterpipe having a transverse head provided with branches connected with the non-perforated portions of the first-mentioned branches, and

steam-conveying pipes connected with and leading from the tank.

7. The combination of a water-tank, an exhaust-steam pipe extended into said tank and perforated in the latter, a water-pipe opening into said exhaust-steam pipe above the perforated portion thereof, a second tank in communication with the first tank, a feedwater pipe leading from said second tank, a pipe extended from the second tank to the water-pipe, and a branch extended from the exhaust-steam pipe and connected with that pipe which extends from the said second tank to said water-pipe.

8. The combination of a Water-tank, an exhauststeam pipe extended into sald tank and perforated therein, a water-pipe opening 7 into said exhaust-steam pipe above the perforated portion thereof, a second tank, a plu rality of pipes connecting the first and second tanks, and a pipe leading from the second tank, for conducting liquidized steam therefrom.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
